Fano resonance enhances x-ray intensity
Nuclear resonant scattering of x rays is an important method to probe the dynamics and structure of condensed matter. As the bandwidth of...
Generation of transient nuclear inversion using XFEL
We collaborate with Adriana Pálffy-Buß from university Würzburg and show that transient nuclear population inversion can be coherently...
Air Laser Gain & Population Inversion
The mechanism of laser-like emission at 391 nm from nitrogen gas irradiated by a strong 800 nm pump laser and a weak 400 nm seed laser is...
